Etruscan Shrew - Hunting and Feeding

Hunting and Feeding

Because of its high ratio of surface area to body volume, the Etruscan shrew has an extremely fast metabolism and must eat 1.5–2.0 times its body weight in food per day. It feeds up to 25 times per day, mostly on various invertebrates (insects, their larvae, earthworms, etc.), as well as small vertebrates (the young of frogs, lizards and rodents), and can hunt prey of nearly the same body size as itself. It prefers species with a soft, thin exoskeleton, so avoids ants when given a choice. Grasshoppers, where common, are often regular prey. It kills large prey by a bite to the head and eats it immediately, but takes small insects back to its nest. When hunting, the Etruscan shrew mostly relies on its sense of touch rather than vision, and may even run into its food at night.
